What is the skin barrier?
A strong and healthy skin barrier is crucial for maintaining healthy skin. The skin is the body's largest organ and acts as a barrier between the body and the environment. The skin barrier consists of the stratum corneum, the outermost layer of the skin, as well as the lipids and protein structures found between skin cells.
The stratum corneum is made up of dead skin cells that act as a mechanical barrier against harmful substances. The lipids in the skin barrier, such as ceramides, cholesterol, and fatty acids, help retain moisture and protect the skin from dehydration and irritation. The protein structures, such as filaggrin and involucrin, strengthen the skin's structure and resist harmful substances.
If the skin barrier becomes weak, it can lead to problems such as dry skin, itching, redness, and inflammation. If the skin barrier is severely damaged, it can lead to skin diseases such as eczema and psoriasis. Therefore, it's important to take care of the skin barrier by choosing the right skincare products and avoiding harmful factors.
How do you maintain healthy skin barrier?
To prevent and strengthen a healthy skin barrier, it's important to choose the right skincare products that contain nourishing ingredients such as hyaluronic acid, squalane, ceramides, and antioxidants. These ingredients help strengthen the skin barrier, protect against free radicals, and reduce inflammation.
In addition to using the right skincare products, a healthy lifestyle can also help maintain a healthy skin barrier. Avoid over-cleansing your skin with hot water and excessive sun exposure, as UV rays can damage the skin barrier and lead to dry skin and wrinkles.
Stress and lack of sleep can also negatively affect the skin barrier's ability, so it's important to prioritize relaxation and sleep. A healthy diet that is rich in fruits and vegetables helps protect the skin against harmful substances and strengthen its barrier function.
